For residents of Pennsylvania, particularly within the historic and populous city of Philadelphia, StormWindows Services provides advanced impact window solutions. While not facing tropical hurricane threats, the state is susceptible to severe thunderstorms, strong winds, and winter storms that can cause significant damage to properties. Our impact windows are engineered to offer superior resilience, safeguarding your home or business against the diverse weather events impacting the Commonwealth.
Pennsylvania's climate features four distinct seasons, including periods of severe thunderstorms in the spring and summer that can produce high winds and damaging hail, along with significant winter storms bringing heavy snow and wind. The housing stock in Philadelphia is diverse, ranging from historic row homes to more modern constructions, each requiring specific considerations for window upgrades. Permitting and building codes in Pennsylvania focus on structural integrity, energy efficiency, and safety, with specific requirements for wind resistance in certain applications. Our impact windows are designed to meet these rigorous standards, providing enhanced protection against windborne debris and extreme weather, ensuring the long-term security and comfort of your property.
An impact window is a fortified window designed to withstand extreme weather conditions, including high winds and projectile impacts. It features laminated glass, where a strong interlayer is bonded between two panes of glass. This construction prevents the glass from shattering, maintaining the window's structural integrity upon impact.
The main drawbacks of impact windows are their higher initial cost compared to standard windows and a potential for slightly reduced light transmission due to the laminated glass. Some users may also notice a minor distortion in visibility. The weight of the glass can also necessitate reinforced framing.
The 'highest rated' impact window is generally considered one that meets or exceeds stringent testing standards such as those established by Miami-Dade County (TAS 201, TAS 202, TAS 203) and ASTM E1886/E1996. These certifications indicate superior performance in impact resistance and cyclic pressure testing.
The cost of a single impact window is influenced by its dimensions, the frame material used (e.g., vinyl, aluminum), the specific type of laminated glass, and any additional features. The complexity of the installation process, including the need for custom framing or structural adjustments, also affects the overall expense.
The average cost for hurricane windows is determined by a variety of factors, including the total number of windows required, their specific measurements, the chosen frame materials, and the impact resistance ratings mandated by local building codes. The scope and intricacy of the installation project are also significant cost factors.
An impact window is a robust window system engineered to resist significant forces from windborne debris and extreme pressure fluctuations. It comprises laminated glass, where a tough interlayer adheres the glass panes together, preventing them from breaking apart and thus maintaining the window's barrier function.
